BooksThe Doctor Who Merchandise site has a page up about the third edition of AHistory which answers all the questions I posted earlier and a few more. The new edition covers about fourteen hundred stories (over a thousand more than ever appeared on television). Here's the run down of what's in store:

"this Third Edition covers all Doctor Who TV episodes through Series 6 starring Matt Smith; all New Series Adventures up through The Silent Stars Go By (#50); the Big Finish audio range up through Army of Death (#155); all Torchwood episodes, novels and comics up through Series 4 (Miracle Day); all The Sarah Jane Adventures episodes, audios and webcomics up through Series 5; the K9 TV show; all Telos novellas; the IDW and Doctor Who Magazine comics; and a cornucopia of other Doctor Who spin-off series (the Bernice Summerfield novels and audios, Dalek Empire, Iris Wildthyme, Faction Paradox and more)."
